Baseline and stimulated growth hormone ( gh ) , cortisol , luteinizing hormone ( lh ) , follicle - stimulating hormone ( fsh ) , prolactin ( prl ) , and thyroid - stimulating hormone ( tsh ) responses were measured using standard pituitary function tests , before therapy in all and during therapy in 17 out of the 21 patients 用标准的垂体功能试验评估所有21例患者中17例治疗前及期间基础和刺激状态下的生长激素( gh ) ，皮质醇，促黄体生成素( lh ) ，促卵胞生成素( fsh ) ，催乳素( prl )以及促甲状腺激素( tsh )的反应。
In order to investigate the ontogeny of the pituitary prolactin ( prl ) expression of sheep fetuses during gestation , the pituitary glands were collected at days 60 , 90 , 120 of gestation , the first day after birth , respectively . the cells containing the prolactin ( prl ) were detected using immunohis ' ochemistry method 为了研究绵羊胎儿垂体中催乳素细胞( lactotrophs )的发育和功能变化，分别在胎儿发育的第60 、 90 、 120天和出生期采集垂体，利用免疫组织化学方法研究了垂体中催乳素( prolactin ， prl )的表达及其变化。
